“Future agriculture-small woman farmer key”


The status of world agriculture

  • employs more than one billion people
  • the biggest consumer of ever scarcer water
  • huge producer of greenhouse gas emissions

Needed
Investment in water saving technology for food production and fresh water conservation to reverse a 70 percent of water withdrawals and 15 percent of greenhouse gas emissions, much of that from developing countries.

The agricultural business accounts for one trillion dollars of the global economy.

Small farmers who dominate the industry would be the key

to maintaining food supplies for the world’s estimated one billion hungry people.

Recent studies have shown that increasing food production of barley, corn, millet, oats, rice, rye, sorghum and wheat increased by nearly 55 percent are not reducing hunger in the world.

“From 1980 to 2009, developing countries need investment to make them less dependent on food imports and international markets. They should put more emphasis on small scale and less intensive farming, the report said.

Finally governments are reinvesting in agriculture and giving priority to small-scale producers.

“They are recognizing the important role of women, infrastructure, safety nets, and local markets,” it added. “All this holds great potential for eradicating hunger.”

Worldwatch Institute, the author of this report, warned that with nearly seven billion people now in the world, and an increase of up to 40 percent expected by 2050, governments still need to take urgent action.

Our current agricultural practices exacerbated by increasing population, and further economic growth, will add up to sharply higher global demand for food, feed, and fiber and to higher meat consumption,” said the report.

“North Atlantic currents +man = global warming”


Using the natural growth rings seen in corals, scientists have found  huge weather-related Atlantic changes


Scientists have pointed to a disruption or shifts in the oscillation as an explanation for moist or harsh winters in Europe, or severe summer droughts such as in Russia, in recent years.

This drastic change began in the 1970s in north Atlantic Ocean currents that usually influence weather in the northern hemisphere, Swiss researchers said on Tuesday.

The team of biochemists and oceanographers from Switzerland, Canada and the United States detected changes in deep sea Atlantic corals that indicated the declining influence of the cold northern Labrador Current.

It is  the most dramatic change uncharacteristic for this area and raised the possibility of a direct link with global warming.

The Labrador Current interacts with the warmer Gulfstream from the south.

They in turn have a complex interaction with a climate pattern, the North Atlantic Oscillation, which has a dominant impact on weather in Europe and North America.

Scientists have pointed to a disruption or shifts in the oscillation as an explanation for moist or harsh winters in Europe, or severe summer droughts such as in Russia, in recent years.

For nearly 2,000 years the sub polar Labrador current off northern Canada and Newfoundland was the dominant force, but that pattern appeared to have only been repeated occasionally in recent decades.

“Now the southern current has taken over, it’s really a drastic change,” Schubert told AFP, pointing to the evidence of the shift towards warmer water in the northwest Atlantic.

The research was based on nitrogen isotope signatures in 700 year old coral reefs on the ocean floor, which feed on sinking organic particles.

While water pushed by the Gulfstream is salty and rich in nutrients, the colder Arctic waters carried by the Labrador current contain fewer nutrients.

Changes could be dated because of the natural growth rings seen in corals.

“The researchers suspect there is a direct connection between the changes in oceanic currents in the North Atlantic and global warming caused by human activities,” said EAWAG in a statement.

“Bombing the moon for water !! “


The LCROSS mission was designed to bomb two spots in a crater on the surface of the moon’s south pole to search for water. These impacts created craters by throwing tons of debris and potentially water ice and vapor above the lunar surface. The impact released materials from the lunar surface that were analyzed for the presence of hydrated minerals to tell researchers if water is there or not.

The Shepherding Spacecraft (SS) and Centaur rocket were launched together with another spacecraft called the Lunar Reconnaissance Orbiter (LRO). All three were connected to each other for launch, about one hour after launch, the LRO separated. The SS guided the Centaur rocket through multiple Earth orbits, each taking about 38 days.
Next the rocket separated from the SS hit the moon’s surface going more than twice the speed of a bullet. A large plume or cloud of lunar debris could be seen. As the plume rose, the SS’s cameras, took pictures of the rocket’s descent and impact into the moon and its other instruments analyzed the material . Four minutes later, the SS followed almost the exact same path as the rocket, descending down through the plume and analyzing it for water (ice and vapor), hydrocarbons and hydrated materials.

In comparison, the sands of the African Sahara are 2 to 5 percent water, and the water is tightly bound to the minerals. In the lunar crater, which lies in perpetual darkness, the water is in the form of almost pure ice grains mixed in with the rest of the soil, and is easy to extract. The ice is about 5.6 percent of the mixture, and possibly as high as 8.5 percent of it, Dr. Colaprete, the Principal Investigator for the Lunar Crater Observation and Sensing (LCROSS) mission said.

When was the scientific principal of respecting new lands and environments, disturbing as little as possible abandoned?

“Looping intermingling deep currents may determine ice age”


Radiocarbon data taken from 30 sediment cores at various locations in the North Pacific indicate that the earth’s climate is regulated largely by the world ocean’s circulation.

This density-driven loops of currents brings warm surface water to the polar regions and transports cold water away. As poleward flowing salty waters cool in the North Atlantic, they become so heavy that they sink. This sinking acts as a pump for the ocean’s conveyor belt circulation.

In the past the North Atlantic branch of the conveyor belt circulation was shut down by melting ice sheets, which in turn released so much fresh glacial meltwater that the sinking of cold water in the Nordic Seas stopped and the Northern Hemisphere was plunged into a deep freeze around 17,000 years ago

This icy deep water spilled out of the subarctic North Pacific at depths of 2000-3000 meters (6,561.7 – 9,842.5 feet) merged into a southward flowing deep western boundary current with a warm, strong poleward current formed at the surface. These conjoining currents gave off lots of heat into the atmosphere.

The deep churning flow of water in the Pacific may have stirred up old carbon-rich deep waters,which would also increase the atmospheric CO2 concentration further warming and accelerated the glacial meltdown.

A computer “earth system model” was run under conditions that mimicked the catastrophic meltwater discharge from the retreating ice sheets 17,500 – 15,000 years ago and disrupted the heat The North Pacific Ocean served as a kind of global backup generator to partly offset There are many complex changes that took place in the oceans of the world during these periods of climate change.

“Tarball stew coming to beach near you”


What are tarballs anyway?

Tarballs can be small to large chunks of crude oil and debris. They may be  dark in color congealed oil globs that stick to our feet, skin, sand, rocks, plants and soil.

(Example only tarballs depicted in image to the right.)

During the first few hours after a crude oil spill, the oil spreads into a  slick. Winds and waves tear the slick into smaller patches that are scattered over a much wider area. Weathering changes  the appearance of the oil.
First, the lighter components of the oil and methane gas mixed with it evaporates, leaving the heavier crude behind. Then some of this crude mixes with water to form an emulsion that often looks like reddish dark brown chocolate pudding. This emulsion is much thicker and stickier than the original oil. Winds, temperature, weather and waves then continue to stretch and tear the oil patches into smaller pieces, or tarballs. Hard and crusty on the outside while being soft and gooey on the inside, like a toasted marshmallow. tarballs may be as large like the one in the picture above or small coin-sized.

Tarballs are very persistent in the marine environment and if picked up by the deep ocean currents can travel long distances. The damage this goo reeks on the environment and all living tings and people is unknown.   Do not let children, animals  or pregnant women play with tarballs or on oily beaches.

Caution
If you are especially sensitive to chemicals, including the hydrocarbons found in crude oil and petroleum products avoid contact with them. They may have an allergic reaction or develop rashes even from brief contact with oil.

Contact with oil should be avoided.

If contact occurs, wash the area with soap and water, baby oil, or a widely used, safe cleaning compound such as the cleaning paste sold at auto parts stores. Avoid using solvents, gasoline, kerosene, diesel fuel, or similar products on the skin. These products, when applied to skin, present a greater health hazard than the smeared tarball itself.

Report tarball sightings

If you notice unusual numbers of tarballs on the beaches, call the U. S. Coast Guard any time at 800-424-8802.

“Bristol Bay Alaska save the endangered whales, salmon and other wildlife”


Another mega-company Anglo American and Mitsubishi wants to turn the pristine area near Bristol Bay, Alaska area over to be mined.
The Pebble Mine is run by another Japanese mega corporation the Mitsubishi Corporation.

Please sign our new Petition of Protest so that your voice can be heard loud and clear at Mitsubishi’s annual Shareholders Meeting in Tokyo on June 24, 2010. Click here to let your voice be heard.

Killer whales may go extinct

Mitsubishi and its share holders wake up!
SAVE BRISTOL BAY

Bristol Bay is a unique American natural treasure.

Beluga whale

  • Home to orcas and beluga whales, wild moose and caribou, and one of only two populations of freshwater harbor seals in the world

It’s world-class salmon runs that support thousands of sustainable jobs in fishing and tourism as well as Alaska Natives who depend on the salmon for food. Click here to let your voice be heard.

What do they propose to do?

  • Put a 2,000-foot-deep open-pit mine in the heart of America’s wilderness in a known earthquake zone.
  • The Pebble Mine’s colossal earthen dams are supposed to hold back some 10 billion tons of mining waste mixed with toxic chemicals. These dams never work forever. These dams are  disasters waiting to happen.

Problems  in the exploration phase

In April 2010 even without the mine in full swing, the companies had taken water from 45 unauthorized stream segments, the Anchorage Daily News reported. The exploration was temporarily halted.

Permits have been reinstated allowing Pebble Limited Partnership to continue exploring copper and gold deposits in southwest Alaska, the state Department of Natural Resources said Friday.
But the partnership still needs permission from the state’s Department of Fish and Game to work in fish habitat in order to begin drilling again this year.
All ready the Pebble Mine before it goes into full-scale operation, it will permanently destroy over 60 miles of salmon habitat.
If salmon runs collapse, so could the entire ecosystem and the communities that rely on salmon for their very subsistence.

Please stand with the Alaska’s Native communities and lovers of nature everywhere by making your voice heard at Mitsubishi’s Shareholders Meeting.

Don’t allow this mega corporation that sells so many cars, trucks, and electronics in the United States sacrifice one of America’s most spectacular pieces of endangered wilderness and the bioms dependent on it.  Click here to let your voice be heard.

Will Mitsubishi rethink this destructive venture when faced with worldwide opposition?

It did 10 years ago. Click here to let your voice be heard.
